Abstract

A hybrid four-hole AsSe2-As2S5microstructured optical fiber(MOF) is fabricated by the rod-in-tube drawing technique. The core is made of AsSe2glass and the cladding is made of As2S5glass. The material refractive indices of the core and the cladding are ∼2.832 and ∼2.219 at the wavelength of ∼2.8 μm, respectively. The calculated zero-dispersion wavelength of the AsSe2-As2S5MOF is 2.759 μm. Soliton self-frequency shift with a soliton central wavelength from 2.986 to 3.419 μm is observed when the AsSe2-As2S5MOF is pumped by an optical parametric oscillator at the pump wavelength of ∼2.8 μm. At the same time a blue-shift dispersive wave is emitted by the soliton.
